DEDA RS4 DB wheelset

The new RS4DB defines a new standard for performance and 

lightness of a tubeless disc brake wheelset. Wheels feature a 38mm 

rim profile and a 26 mm width (19mm internal) designed to be fast and 

light on any course. The full carbon rim is molded with a technology 

that allows the differentiated distribution of the thickness. The rim 

is reinforced in the nipple area and has reduced thickness out of the 

nipple area. This bring an important weight saving on the external 

part to reduce the inertia of the wheel. RS hubs have been completely 

reengineered compared the SL generation. More aero and lighter to get 

a total weight saving of 80g. The rear hub features a 2-ratchet system 

for the freehub engagement. A smaller ratchet is located in the freehub 

body while the bigger is located inside the hub flange for a better pedal’s 

force transmitting. The hubs design considerably improves the wheels 

smoothness for superior speed. The rim is built with the tubeless-ready 

technology to be compatible with clincher and tubeless tires.

The internal nipples improve aerodynamics, while the self-locking ABS® 

system prevents the loosening of the nipples and spokes. 

Available for Shimano, Campagnolo and Sram cassettes.
